Indeed, the medical information has become the source of a tongue-in-cheek conspiracy theory, similar to one that plagued Mr Trump’s predecessor.

Those who accused Barack Obama of faking his birth certificate to prove his US citizenship, which included the new president, were known as birthers – and one clever clogs has come up with a new name for the Trump medical theorists.

Has anyone coined "girther" for those who belive the president weighs more than his doctor reports?

Well, some point to discrepancies in his height measurement. Many, including columnist Gersh Juntzman, shared a picture of what appears to be Mr Trump’s driving licence claiming he was 6ft 2in (1.88m) in 2012 – the same height Google has for Mr Trump when searched.

He tweeted: “Now his doctor says he’s 75 inches. And that one inch makes his BMI ‘overweight’ not ‘obese.’ I’m a #girther because old men don’t GROW an inch!”

Others decided to give comparisons, pointing to the fact former president Mr Obama is listed as 6ft 1in, two inches shorter than Mr Trump – saying he appears a similar height in pictures at last year’s inauguration.

Some pointed to Mr Trump’s weight, comparing him with sports stars – such as the NFL’s Minnesota Vikings running back Latavius Murray, who has the same height and weight measurements according to one Twitter user.
